November 2, 2000 was the last time all humans were on the planet together. Since then at least one person has remained on the international space station.
Carl Sagan convinced NASA to turn the Voyager Spacecraft towards earth and take the iconic “Pale Blue Dot” photo nearly 4 billions miles away from earth.
Those who see Earth from space experience “The Overview Effect:” A remarkable sense of connection with the rest of the human race, and a desire for world peace.
Due to gravitational time dilation the core of the earth is approx. 2.5 years younger than surface. Higher gravitational potential causes time to move faster. For example, over the course of earth’s history, a clock at the top of Mt. Everest would be approx. 39 hours fast than at sea level.
Superabundance is the belief, that no matter how many natural resources humanity uses, the planet will continuously replenish the supply. This, actually is the myth.
Because of the movement of the Earth’s tectonic plates, Australia is drifting so fast that they plan to adopt a moving GPS system by 2020 to compensate for the changes.
The average person will walk approximately the distance of 3 times around the planet in their lifetime.
L = Sd x D / C
L = (7500 steps) (0.672 m) x (71 years x 365 days) / 40 075 000 m
L = 3.26 laps
Before trees were common, Earth was covered by giant mushrooms.
“The Blue Marble” is the only whole-earth photo taken by human hands. No one has since been far enough from earth to take a similar picture.
Even if the Earth was somehow separated from the Sun, the temperature of the molten core would be high enough to sustain life on the deep sea ocean floor.
